APPARATUS FOR THE MANUFACTURE OF PIPE.

SPECIFICATION forming part of Letters IPatent No. 566,611, dated August25, 1896.

Application filed June 6, 1896. Serial No. 594,499. (No model.) i

To all whom it may concern.-

Be it known that I, THOMAS B. NUTTALL, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented or dis covered certain new and usefulImprovements in Apparatus for the Manufacture of Pipe, of whichimprovements the following is a specification.

The invention described herein relates to certain improvements indraw-benches for the manufacture of pipe, and has for its object aconstruction wherein the pipe-bench is movable transversely in front ofthe heating- 1 5 furnace, so that it may be brought in line with any oneof a number of skelps arranged within the furnace, such movable benchbeing used in connection with a stationary draft mechanism having anadjustable connection to a draft-buggy on the bench and adapted to beshifted by the bench in its transverse move ment.

The invention is hereinafter more fully described and claimed.

2 5 In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view of my improved apparatus for manufacturingpipe. Fig. 2 is a side elevation of the same; and Fig. 3 is an endeleva- 0 tion, portions of the draft mechanism being shown in section.

In the practice of my invention the bench 1, which is formed with alongitudinal slot therethrough and has the bending or welding 3 5 die 2secured on its front end, is provided with lateral brackets 8, havingfriction rollors 4 mounted therein and adapted to move alongsupporting-rails 5, arranged in front of and parallel, or approximatelyparallel, with the furnace and at suitable distance therefrom. The underside of the rails 5 is provided with toothed bars 6, with which pinions7 on the shaft 8 are adapted to intermesh, said shaft being mounted inbearings 9, suspended from the bench 1. By the rotation of this shaftthe bench can be shifted laterally to any desired position in front ofthe furnace.

About midway of the middle of the furnace is arranged a horizontal rail10, supported. at

its ends by frames 11, one located immediately in front of the furnaceand the other at a distance therefrom greater than the desired traverseof the pipe-drawing buggy. On the rail 10 is mounted a sleeve 12,provided with collars 12*, to whichis secureda sector-frame 5 5 13,consisting of two side plates secured together at the ends and laterallybraced by bars 14 to the ends of the sleeve. Between collars on thesleeve 12 is mounted a hub 15, provided with a socket l6, projectingradially 6o therefrom and between the plates of the sector, which servesto hold the socket as against lateral movement in a direction parallelwith the bench, while free to turn in a vertical plane at right anglesto the bench. One end of a bar 18 is arranged within the socket,

so as to move back and forth therein, while the opposite end of said baris pivotally connected to the draft-bar of the buggy. This buggyconsists of slides 19, arranged in suitable guideways in the bench, anda draft plate or bar 20, attached to said slides about midway of itslength and having one end connected to the bar 18, as hereinbeforestated, while its opoosite end is provided with a hook 7 5 or othersuitable means whereby the pipetang or pipe-tongs may be connected withthe buggy. In order to shift the sleeve 12 and the buggy'to which thesleeve is connected from and toward the furnace, an endless rope 8o 21is connected at one end to one of the sectorplates, passes rearwardlyover a guide-pulley 22, mounted in the rear frame or standard, around adriving-drum 23, over guide-pulleys 2i and 25, mounted on the rear andfront frame, respectively, and having its end con nected with the sleeve12. It is preferred to connect that part of the rope which shifts thebuggy during the bending or welding of a pipe as near as possible to thebuggy itself to 0 prevent lateral strains on the connections between thesleeve and buggy, although it may be connected directly to the sleeve.lhe part of the rope which returns the buggy to the front of the benchis preferably connected 5 with the sleeve above the rail 10, so as to beout of the way of the workmen.

To one side of the bench are secured tubes 26, whose opposite ends fitover one end of a series of bars 27, the outer ends thereof beingattached to a trough 28,into which the finished pipes are rolled, thetubes and bars serving as skids for the transfer of the pipes from thebench to the trough.

It will be observed that as the bench is shifted back and forth in frontof the furnace the socket Will be correspondingly shifted between thesector-plates, the bar 18 sliding in and out of the socket as the benchmoves toward or from middle position.

I claim herein as my invention- 1. In a pipe bending or Weldingapparatus, the combination of a bench, abending or Welding die, meansfor shifting the bench laterally, a buggy mounted on the bench, acentrally-arranged draft mechanism, and an we tensible connectionbetween the draft mechanism and the buggy, substantially as set forth.
